The Portland Bureau of Transportation was supposed to present a report to the City Council on Wednesday outlining new revenue options for roads and travel. The city clerk's office listed the scheduled presentation on its website as recently as last week.

But city officials have postponed the public release of the report until the new year, saying it's not ready yet.

Mayor Sam Adams' 2012-13 budget called for such a report by Jan. 1, 2013, when Adams' time as mayor ends.

The idea was to address Adams' concern that the Transportation Bureau lacks adequate revenue for maintenance and other projects despite the fact that gas tax receipts -- a big source of the bureau's discretionary dollars -- have grown. Adams and the bureau's director, Tom Miller, argue that they're not growing enough.

The draft indicates Portland may consider a new street maintenance fee -- an
idea that Mayor-elect Charlie Hales raised unsuccessfully when he was a
city commissioner in 2001 and that Mayor Sam Adams tried and failed to
get in 2008, when he was also a city commissioner.

It also addresses the possibility of a new Portland gas tax, a commercial parking tax
such as the one in Seattle, inflation-indexed rates for parking meters
and city-owned garages, higher parking rates for special events and
general obligation bonds.

A spokeswoman for the bureau, Cheryl Kuck, said the agency would share the report with members of the City Council individually before the end of the year.
